Windows 7: LAN connection - Unidentified Network - No Internet

HELP!!!!!

I have installed Win 7 - Build 7100



It worked for 2 hrs and since then all I get is the network icon in the bottom right with the yellow triangle. It states unidentified network - no internet access.

How can I cure this.....

It is a NVIDIA Network controller on a ASUS Striker II Extreme board.

I have the same problem here on a Dell Dimension E520 with an Intel 82562V Gigabit card, but try this: right-click on the network connection icon in the system tray and choose Open Network and Sharing Center. Near the top of the left hand pane, click Change Adapter Settings. Right-click your network adapter and click Disable. After it's finished disabling, right-click it again and click Enable. That seems to clear up the problem here, although I have to go through the same process whenever I reboot.

No just returns to the same error!!!!

It used to work until I did the latest security update. I may try removing that and seeing...

I had the same problem when I first upgraded to Win 7 build 7100. I found that the network card advanced settings 'WOL & Shutdown Link Speed' had defaulted to 10Mps First. I changed it to 100Mps First and not had a problem since.

Boogieman: is that a Realtek or an Intel card? I just checked my PC with the Realtek, and it has that setting available. It's set to 10Mbs first, though, and everything is working fine.

The PC with the Intel card, on the other hand, doesn't display that option, and that's the one that's having the problem.

May be a silly question how do I check this and change it

My computer has a Realtek card. The change from 10 to 100 got me a network connection that I didn't have. Maybe a driver update for your Intel card or try a Realtek card instead!

Lowsider: Right-click the network icon in the tray. Select Open Network and Sharing Center. In the left hand pane, click Change Adapter Settings. Right-click your adapter and select Properties, then Configure, then the Advanced tab. Scroll down and you'll see the option (probably last in the list).

Boogieman: I've been sniffing around on the Intel site and there are some drivers which appear to be newer, but installation fails -- "not compatible with this operating system".

Hopefully the white coat guys are working on a Windows 7-compatible update.

There is no such option. Mine is a nVidia Network controller on the motherboard... This is really starting to hack me off....

Ah, yes. I should have reiterated that this is just for the Realtek card (thought you had one of those). Sorry.

On the bright side, hopefully the fact that this does not appear to be an isolated annoyance means that it'll be visible on the Microsoft and network vendor radar systems and dealt with before Windows 7 goes gold.
